From: Richard Sandiford <rsandifo@gcc.gnu.org> To: gcc-cvs@gcc.gnu.org Subject: [gcc r13-2434] aarch64: Remove lazy SIMD builtin initialisation Date: Mon, 5 Sep 2022 13:14:58 +0000 (GMT) [thread overview] Message-ID: <20220905131458.2F65A3857016@sourceware.org> (raw) https://gcc.gnu.org/g:d29ecf23f0b046de720a25171c3b3980fa8a0a22 commit r13-2434-gd29ecf23f0b046de720a25171c3b3980fa8a0a22 Author: Richard Sandiford <richard.sandiford@arm.com> Date: Mon Sep 5 14:14:44 2022 +0100 aarch64: Remove lazy SIMD builtin initialisation At one time the aarch64 port registered the Advanced SIMD builtins lazily, when we first encountered a set of target flags that includes +simd. These days we always initialise them at start-up, temporarily forcing a conducive set of flags if necessary. This patch removes some vestiges of the old way of doing things. gcc/ * config/aarch64/aarch64-protos.h (aarch64_init_simd_builtins): Remove prototype. * config/aarch64/aarch64-builtins.cc (aarch64_simd_builtins_initialized_p): Delete. (aarch64_init_simd_builtins): Make static. Remove protection against multiple calls. * config/aarch64/aarch64-c.cc (aarch64_pragma_target_parse): Remove lazy SIMD builtin initialization. * config/aarch64/aarch64.cc (aarch64_option_valid_attribute_p): Likewise.
